. To all whom t may concern.'

Be it known that I. CHBISTLA'N PAUL HA- GENLooHER, a* citizen of the United States, residing at APhiladelphia, Pennsylvania,

have invented certain new and 'useful Improvements in Roller Bearings, of which I declare the following to'be a full, clear, and exact description.

Thisl invention relates. to improvements in roller bearings. I

The principal object of my invention is to provide a roller bearing which is so constructed that it' may be satisfactorily'used as a replacement for the ball-bearings used l5 in the wheel'hubs of a Ford automobile.

Another object of my invention is to provide a roller lbearing having-two seating surfaces perpendicular to each other and thus permitting the seating of the bearing in a positive manner in the wheel hub of a Ford automobile.

. Further objects, and objects relating to economies of `material and details of construction, will deinitely appear from the detailed .descriptionl to follow. I accomplish the objects of my inventionv by the devices and means described inthe following specification. My `invention is clearly vdefined and pointed `out in the lappended 50 claims. A structure constituting a preferred embodiment of my inventionis illustrated in the accompanying drawing, forming part of thisl specification, in which;

Figure I is a sectional view through av part of a wheel hub and a bearing constructed in accordance with my invention.

Figure II is a plan view of the outer bearing member, looking from lthe left in Figure I, and j Figure. III is a plan view of the outer bearing member, looking from the right in Figure I.

In the drawing. similar reference numerals refer to similar parts throughout the several views.

Referring to the drawings, I have shown a roller bearing comprising the inner bearing or cone member 1, having the external conical bearing surface y2, and the outer bearing or cup member 3, havin an in-y ternal conical bearing surface 4. plurality of ta ered rollers 5 are interposed between anv roll upon said bearing surfaces each end of each roller. 55

.' This lbearing is intended for use as a re,- placement for the ball-bearings used in the wheel hubs of a Ford automobile and a part of such a hub is shown at 7 in FigureI. This hub has a cup shaped recess to receive 00 the'bearing and a planeV surface 8 adjacent the edge of the central opening through which the shaft or spindle passes. This surface 8 is perpendicular to the axis of the hub. There is also a cylindrical' surface 9, near the outer edge of the cu shaped recess which is co-axial with t e hub and therefore perpendicular to the surface v8. In assembling the bearin 1n the hub it is essential that the axis of t e bearing should coincide with the axis ofthe hub. To insure such perfect coincidence I provide an external cylindrical surface 10 upon the outer bearing member which 'seats upon the cylindrical surface 9 of the recess in the hub and assists in bringing the bearing to perfect alinement in the hub. I also provide, on the outer ,bearing member, a seating surface 11 which lies in a plane perpendicular to the axis of the bearing and is nearly in line with the small ends of the rollers 5. This surface 11 seats on the plane surface 8 in the hub and, together with the Asurface 10, maintains the bearing in the hub with its axis absolutely coincident with the axis of the hub. The-surfaces 9 and 11 of the outer bearing member are connected by the external partly spherical surface 12.. Retaining rings 13 are seated in grooves' in thelcone member 1 and abut the shoulders 14. The flanges of the retaining rings 13 overhang the ends of the retaining pins 6 and loosely retain the rollers in assembledv relation with respectto the-inner bearing member. The end of the outer' bearing member is substantially in line with the small ends of the rollers and hence I cut away on the inner side of the outer bearing member to provide the cup-shaped surface 12 within which the flange of the retainingV 100 l ring 13 is housed. e

I am aware that the particular embodi-` ment of my invention, which I' have de-l scribed here, is susceptible of considerable variation without departing from the s irit of my invention and hence I desireto c aim the same broadly, as well-.as specifically, as indicated by, the appended claims.

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent, is l `l. An antifriction bearing comprising an inner and anouter bearingA ring, a clrcle of tapered rollers disposed between said rings the outer of which rings is cylin rical in contour throughout a portion of its extent and tapered throughout the remaining portion of its extent said cylindrical and tapered parts forming a juncture and the surface of said 'tapered portion being so arranged that a plane tangent thereto inter? sects the axis of a roller and means for retaining said rollers in position.

Athe hub., the other 'side of said ring being substantially cone-rrustum shaped, the 'atend of said rin being in abutting relation with said shoul er and that portion of the ring between the cylindrical side and flat end 4being free of the conventional inclined wall of said hub.

' In testimony whereof, I affix my signature. t
